摘要: 运用VB.net、Intel Fortran等软件对长江口风暴潮集成预报系统进行升级与改进.引入SWAN并行计算模式，显著提高波浪模式的计算效率，解决了快速预报中考虑波浪计算的时效性问题.优化流场模式代码，进行模块化设计，提高流场模式的计算效率.对软件界面进行改进，增强了人机交互界面友好性，提高了软件兼容性与稳定性.通过5个台风暴潮的计算对比，结果表明新系统保持了原预报系统计算精度，并提高了系统整体预报效率.在本文的硬件环境中，不考虑波浪计算时，预报时间节省60%；考虑波浪计算时，预报时间节省68%.Abstract: This study focuses on the upgrade of an integrated storm surge forecasting system for the Changjiang Estuary with development tools such as VB.NET, Intel Fortran, etc. The forecasting efficiency with wave consideration has significantly improved by the implementation of SWAN parallel computation. Hydrodynamic model could provide much faster forecasting with the optimization and modularization of the source code. New software interface was designed to improve the compatibility and stability. The comparison between the original and upgraded version is given with 5 storm surge simulation, with an aim to show the system improvement on forecasting efficiency and precision. It shows the model precision of upgraded version is guaranteed. The efficiency is quantitatively increased by 68% and 60% with consideration and neglecting of wave effect, respectively.
